Standard Operating Procedures for Installation and Maintenance of Shaft Locks

Abstract:
This document outlines the standardized procedures for the installation and maintenance of shaft locks, applicable to both steel and wooden doors. The process emphasizes the correct orientation of the lock body, the installation of the lock core, and the securing of the shaft lock cover to ensure operational efficiency and security. The procedures are designed to ensure that the lock mechanism functions smoothly without any obstruction, with specific attention to the direction of the lock body, the positioning of the lock core, and the fastening of the screws to avoid damage to the door surface.

1. Introduction:
   Shaft locks are essential components in ensuring the security and functionality of door systems. Proper installation and maintenance are critical to their performance. This guide provides clear instructions for technicians on the correct installation and maintenance practices for shaft locks, focusing on efficiency, precision, and safety.
2. Installation Procedure:
   2.1 Lock Body Installation:

• The shaft lock is ambidextrous, meaning it does not differentiate between the left or right side. Adjust the direction of the lock body accordingly when switching between left and right door leaves.
• Mount the lock body on the upper side of the door leaf, ensuring the latch is positioned downwards and the lock core hole is upwards.
• For steel doors, use M4 screws for direct mounting. For wooden doors, insert wood screws by hammering them one-third of the way in, then screwing them in two-thirds of the way with a countersink bit. Avoid hammering the screws all the way in directly. Ensure the lock faceplate is flush with the door leaf surface (average operation time: 40 seconds).

2.2 Lock Core Installation:

• Remove the key from the lock core, align the two screw holes upwards, and insert the lock core from the non-fire side. Secure the lock core with screws from the fire side. If the key cannot be removed, check the orientation of the key (average operation time: 40 seconds).

2.3 Shaft Lock Cover Installation:

• Lay the door leaf flat and align the screws with the connecting rod holes coming through, then tighten the screws (average operation time: 50 seconds).

2.4 Lock Operation Check:

• Turn the key to extend the latch. Rotate the key back 90 degrees to remove it. Ensure the key operates smoothly without any sticking or resistance (average operation time: 10 seconds).

1. Maintenance Guidelines:

• Regularly inspect the lock mechanism for signs of wear or damage.
• Lubricate the moving parts of the lock periodically to ensure smooth operation.
• Check the alignment of the lock body, core, and cover during maintenance checks to prevent operational issues.

1. Conclusion:
   Adhering to the standard operating procedures for the installation and maintenance of shaft locks is crucial for their proper function and longevity. By following these guidelines, technicians can ensure the security and reliability of the door locking mechanisms, thereby enhancing the overall safety of the premises.
